C-peptide of proinsulin is important for the biosynthesis of insulin. C-Peptide was initially thought to have no intrinsic biological activity, but data now indicates multiple biological effects of C-peptide, including binding to cell membranes, activation of signaling pathways, and stimulation of Na+,K+-ATPase and endothelial nitric oxide synthetase.
C-Peptide Synthetic is a single, non-glycosylated polypeptide chain containing 31 amino acids, having a molecular mass of 3020 Dalton and a Molecular formula of C129H211N35O48S .
